Optimal (San Jose, Calif.) said the new Full-Wave SI/PI flow allows users to run simulation on selected signal nets and part of the power/ground nets in O-Wave while PowerGrid simultaneously runs a simulation on the complete power/ground structure, resulting in one complete model.

In a statement, An-Yu Kuo, Optimal co-founder and chief technology officer, said adjacent structure coupling is an important breakthrough that would enable designers to avoid making risk assumptions in order to simplify design geometry. "High-speed designers simply cannot afford to take risks with today's technology that could cost them time and a window of opportunity in the market," Kuo said.

Perpetual licenses of Full-Wave SI/PI flow (which includes PowerGrid and O-Wave) starts at $90,000 per seat.

Optimal was founded in 1995 but remained in "stealth mode" until is started launching products in 2003.
